Ok, i'm also thinking, the dsa-definition will be the right way (pattern-properties with optional "ethernet-") in binding.

Should i use "ethernet-ports" instead of "ports" here? Current dts with mt7530/mt7531 switches using "ports" so i would use it here too. If dsa prefer ethernet-ports now it should be changed in other files too.
